Camellia leaf disease hazards

The危害 of Camellia leaf disease in the later stages of infection can cause the entire leaf to turn brown and dry, leading to excessive water loss and leaf drop. The disease can also affect the plant's growth, impacting flowering.

Causes of Camellia leaf disease

Camellia leaf disease is caused by bacterial infections, typically starting in April and peaking in June and July. Affected tea flowers with (T-J) disease will show black spots, which can even spread to half the leaf, causing leaf drop.

What Medication to Use for Camellia Leaf Disease

Camellia leaf disease is treatable, and fungicides such as zinc omethoate and thiabendazole are generally effective. When using zinc omethoate, it should be avoided to mix with other alkaline pesticides. Spraying the leaves every two weeks for three consecutive times can be effective, preferably in the evening.

Camellia Leaf Disease Control Methods

Leaf disease treatment methods

After Camellia is affected by leaf disease, all infected leaves should be cut off before winter and then sprayed with lime sulfur solution for treatment. Afterward, purchase and spray fungicides to supplement nutrients for the plant and prevent diseases.

Leaf disease preventive measures

Keep the soil clean: The prevention of Camellia leaf disease mainly starts with the soil, so it is essential to keep the soil clean by promptly removing diseased leaves.

Supplement nutrition: It is necessary to maintain the timely supply of nutrients to Camellia plants. During the period of vigorous growth, in addition to supplementing nitrogen fertilizer, also add organic fertilizer and phosphorus and potassium fertilizers.
